- citizens ofthe United States, residing at Los Angeles, in the county of Los Angeles and State of California, Have invented a. new and useful Joint, of'which-the following is a specification- This invention relates to 'a'joint adapted for a variety of uses. For example, it-may be employed in a folding extension horse to detachably unite. the top part to the vertical posts,'as shown in a previous ap lication of ours filed May 10, 1909, Serial l lo. 495,191. The jointis also adapted for. securing tent poles together.' It is also of great value in the construction of portable houses. The joint is adapted for use in, many other situations not herein named.

The object of the invention is to provide a joint whereby two .bars or posts may be detachably secured to each other at an angle to each other, the said joint when secured preventing either of the members so'joined from being drawn away from the other, it being first necessary to unlock the joint be-- fore the joined members can be separated.

Preferably, the invention comprises in combination with the two members joined together, a loop on eachmember whi clrreceives the end of the other member, and one of said loops being movable to jointed or unjointed position, permitting engagement or disengagement of the two members. Thus when the two members are joined together the end of each member projects-into and is at an angle to the loop onthe end of the other member, so that both ends of both members are securely locked by the respective loops, which loops prevent either member from being drawn away from the other.

Referring to the drawings :Figure 1 is a erspective view of tll,j0ll1l3 showing the ars separated; This shows the form'in which a brace is employed. Fig. 2 is a 'perspective vie-w showing the bars jointed together. Fig. 3 is 11 pers ective view of another fprm, in which the race is omitted. Fig. 4 is a side elevation on a reduced scale, showing -the-joint constructed for a different :ingle,.'thc pivoted loop is shown swung intodisengaging position,

is vertical and the post 2.-horizontal, but it should be understood that they may occupy any deSiredpositIon, v vided on its end with a loop 3, the latter,

as shown, being rigidly secured thereto, in-

the present instance by two screws '4, although the 1oop-3-may be attached to the bar 1 by any other desired means. The

end of the bar 2 is provided with a tenon-5- which is of a size forming a perfect fit with The bar 1 is pro in the loop 3. The end of the tenon 5 is slightly curved, referably as at 6, and the edges 7 of the oop 3 are {also preferably slightly curved. Pivoted 0n the end of the bar 2 is: a loop 8,.the, screws 9 forming a pivotal suppoit therefor. The two members may be put together by'firsttinsjerting the tenon 5mto the loo 3, Then the loop. 8

, is swung ;down over t e'loop 3 into the posi- -sition shown in Fig.' 2. Thus when in such position the joint is whatmay .3 ahd thus prevents the. bar 2 from slippingflfarther into the loop 3, while the loop 8 hich engages over t e vents the bar 1 from being moyed -Iawa'y from the bar 2, that is to say, from slipping p 3 which is locked over the tenon 51prevents be termed j ocked,fand' thearts are in ointed position. The curve edge 7 of the loop 3 and loop 3 prethe bar 1 from moving at rightangles to the bar 2. It will thus be seen that when the members are secured together, the end of, each member projects into the loop of the'dther member so that each locks the other, both loopsbeing interlocked. By

swinging back the loop 8 the bar 2 may be quickly withdrawn'from loop 3,,thus the two members may be instantly joined togetherior separated. When joined together the members are securely-held in rigid relation to each other, but if desired, a brace 11 may be employed which at one end is beveled-at 12 and pivoted at 13 to a strap l twhich is secured by a screw 15 to the bar 2, the brace 11 at its other end having a blade 16 with a slot 17, which blade is adapted to project into' a slot 18 formed in the post 1, and the slot 17 of the blade 16 is adapted to be engaged with a pin 19 in the bar l-which extends across the slot 18.

Fig. 2 shows the manner in which the blade 16 is inserted into the slot 18 and engaged by the pin 19. The corner of the blade 16 is rounded, as at 20, to permit the blade to be easily inserted into the slot 18, as by tipping the blade 16 enough so that the slot 17 first engages the pin 19, the blade may be slipped in with a slight rocking mo- .tion, and at the same time 'tenon 5 may be started into-the loop. 3, the tenon 5 being shoved into the loop 3 at the same time the blade 16 is shoved into the slot 18.

11 is omitted.

In Fi 4: the construction is identical with that in ig). 3, except that the end of the post 1? is veled, and the projecting end '3 of the loop 3 is at an angle to the bar 1. Obviously, the loop 3 could be arranged v with its projecting portion at any desired angle other than the angle shown in Fig. t or the straight line position in Fig. 1.

.VVhat we claim is 1. A joint com risin two ham, :1 loop on the end of each ar a apted to receive the end'of the other bar. 2. A joint comprising two bars, a loop on the end of each bar adapted to receive the end of the other bar, one of said loops being pivoted on its bar to swing over the end of .the other loop.

3. A joint com rising two bars, a loop on the endof each ar adapted to receive the end of theother bar, the end of one of said barshaving a tenon to fit within the loop of the other bar, and the loop on the said bar having a tenon being ivoted and adapted to swing over the loop 0 the other bar.

LA joint comprising two bars, a loop on Fig. 3 shows the joint in which the brace the end of each bar adapted to receive the end of the other bar one of said loops being movable to permit its bar to be first in- 4 sorted in the other loop, after which the movable loop is adapted to be engaged over the other loop.

5. A oint comprising two bars, a rigld loop on one bar, a loop pivoted to the other bar, the rigid loop having curved edges over which the pivoted loop is adapte to be swung, the end of the bar having the pivoted loop being curved to permit the swinging movement of the pivoted loop.

(3. A joint comprising two bars, a loop on the end of each bar adapted to receive the end of the other bar, and a brace having a pivotal connection to one of said members, the other member having a slot with a pin across said slot, a blade in the end of said brace, said blade having a slot and adapted to he slipped into the slot in the bar, the slot of the blade being adapted to engage the pin.

'7. A joint comprising two bars, a loop on the end of each bar adapted to receive the end of the other bar, and a brace having a pivotal connection to one of said members, the other member-having a slot with a pin across said slot, a blade in theend of said
